PIPE HANGER ADAPTER This invention relates to a device for the facilitation of installation and repairs of pump systems and wells. The invention is trouble free, sanitary, and lessens the cost of pump installation.

Accordingly, a primary object of this invention is the provision of apparatus for simplifying installation of pump systems in wells and minimizing the cost thereof.

Another object of this invention is the facilitation of repairing the pump system after it has been installed in a minimum of time, cost, and physical effort.

The above and other objects of this invention will become apparent to those skilled in the art after a consideration of the detailed description of preferred embodiments of this invention taken together with the accompanying drawing wherein:

FIG. 1 is a cross-sectional elevational view of the ap paratus;

FIG. 2 is a front elevational view of the adapter;

FIG. 3 is a plan view of the adapter;

FIG. 4 is a bottom view of the adapter;

FIG. 5 is a sectional view taken on line 5-5 of FIG. 2;

FIG. 6 is a sectional view taken on line 6-6 of FIG. 5;

FIG. 7 is a sectional view taken on, line 77 of FIG. 2;

FIG. 8 is an elevational view of asingle pipe hanger adapter embodiment;

FIG. 9 is a front elevational view of the adapter thereof;

FIG. 10 is a sectional view taken on the line 10-10 of FIG. 9;

' FIG. 11 is a plan view thereof;

FIG. 12 is a bottom view thereof;

FIG. 13 is' an elevational view of an adapter lock; and

FIG. 14 is a cross-sectional view of an adapter lock.

Referring in detail to the drawing, there is shown a well casing 30 extending out of the ground 32 and having a well cap 34 on top thereof. Beneath the ground at a point along casing 30 is a threaded well casing T 36 which connects upper and lower portions of casing 30 and has a threaded bore 38 in the side thereof. Threadedly inserted within bore 38 is an offset T casing 40 which leads out of the ground 32.

FIGS. 2-7 clearly show the details of an adapter housing 50 which has a threaded solid top portion 52, a projecting side portion 54 having a longitudinal axis thereof aligned at an acute angle with the longitudinal axis of adapter housing 50, and passageways 56 and 58 having their threaded inlets 60 and 62 at the bottom surface of adapter housing 50 and their outlets and 66 at thesurface of projecting side portions 54.

FIGS. 5 and 6 clearly show in detail a pipe adapter lock 70 having an annular projection 72 near the rear thereof, a pair of opposing tabs 74 projecting from the surface thereof, and a threaded bore '76 at the front thereof. Outlet 66 has an annular groove 80 and a pair of opposing grooved portions 82 in the surface of projecting side portions 82 in the surface of projecting side portions 54. Annular projections 72 and tabs 74 mate with annular groove 80 and grooves 82 fonning a leakproof connection. A smaller diameter adapter lock 78 similarly locks into outlet 64.

An internally threaded sleeve connects top threaded portion 52 with a left leg pipe 92. Pipes 94 and 96 are threadedly connected to inlets 56 and 58 respectively extending therebelow into the well. Pipe 92 is lowered from the top of well casing 30 to a depth where adapter housing 50 is enclosed by T 36. Offset pipes 100 and 102 are inserted in offset casing 40 and are threadedly turned counterclockwise within threaded bore 76 and threaded bore 79 of lock adapter 78 secured to outlet 64.

In this manner adapter housing 50 and the. associated pipes within casings 30 and 40 hang free from any attachment on casings 30 and 40 obviating welding or bolts that have been used heretofore. This invention makes it unnecessary to increase the size of the well casing which has been heretofore necessary when making an offset installation below ground level where standard pipe fittings are used. When there are to be repairs, pipes 100 and 102 are simply detached by turning clockwise and lift leg pipe 92 is simply pulled out from casing 30.

Shown in FIGS. 8-14 is a single pipe adapter housing having a threaded top portion 112 and a single passageway 114 with a threaded inlet 1 l6 and an outlet 118 projecting from the side of housing 110. A sleeve 120 internally threads a lift leg pipe 122 to top portion 112 for dropping adapter housing 110 and pipe 112 threaded into inlet 116 into the wellcasing. An adapter lock 124 is secured to outlet 118 in a mated fit between an annular groove and a pair ofopposing grooves .132 within outlet 118 and an annular projection 134 stance, annular projection 134 may be a sealer ring or.

rubber O-ring. Also, it should be noted that the single pipe adapter embodiment is for both jet and submersible pump installations.

I claim:

p 1. A pipe hanger adapter comprising an upright cylindrical well casing, a generally horizontal cylindrical offset casing detachably secured to and forming a passage to and from said well casing at a point below the ground, an adapter housing positioned within said casing aligned with said offset casing and making no 7 physical contact with the inside surface of the wall of said well casing, a lift leg pipe detachably secured to said housing and extending upwardly in said well casing to a point adjacent the upper end thereof, at least one pipe secured to and extending below said adapter housing in said well casing, at least one pipe insertable within said offset casing and detachably secured to said adapter housing without making physical contact with the inside surface of the cylindrical wall of-said offset casing, means on said housing forming a leak-proof passageway between said pipes, an adapter lock having an annular projection and a pair of opposing tabs projecting therefrom, said passageway having an annular groove and a pair of opposing grooves therein, said annular projection and tabs mating with said annular groove and grooves, said adapter lock having a threaded bore in the other end thereof for securing said 5 second mentioned pipe to said first mentioned pipe in fluid communication.
